a wise investment By robert98 on 1/16/14robert98 would recommend this product to a friendthis product does exactly what it was made to do, easy hook-up perfect for any r/o system.
Great convenience but leak problem By Steve D on 7/10/13Steve D would recommend this product to a friendThis is a great item to have, but it has a rigid plastic 1/4-inch probe section that fits into the supplied T-fitting. But it has a slow leak between the rigid plastic insert and the quick-lock fitting which caused me to have to put a ball valve in my input water supply just to turn it off between uses so that my otherwise dripless RO system and connectors wouldn't drip, drip, drip day and night.
water quality By Billy on 5/30/13Billy would recommend this product to a friendNever tested my ro system. Since I just bought the upgrade and booster pump from 75 gallon to 150 gallon. I had to get some way to see my water quality. Worth every penny.
Excellent! By Loren on 4/22/13Loren would recommend this product to a friendHooked it up out of the box, was getting a reading instantly. Great for letting you know when you need to replace your filters, so in a sense saves you money. And keeps your aquarium clean and in tip top shape. I will not go with out one anymore.
A needed item if you have a RO/DI system By Rob Coberg on 12/3/12Rob Coberg would recommend this product to a friendI order one of these units a week or so ago, good thing I did . I would have never known my tds were hi as they were. I am taking corrective action to get it to 0 tds where it should be.
Must Have By dgil71 on 7/10/12dgil71 would recommend this product to a friendHave an RO system? Then you must have one of these. Accurate reading, super easy to install!
Works great. Best way to determine if RO/DI system is ok By Tony on 6/5/12Tony would recommend this product to a friendThe Single Inline TDS meter does a great job of detecting TDS in my RO/DI system. I use it once every two weeks to monitor for need for filter change. Easy on/easy off. Great price.
Use it anywhere By John on 4/26/12John would recommend this product to a friendI put this meter in front of my RO unit to monitor the TDS of my well water. When I see it going up I know it's time to do a little home maintenance. Handy meter for sure

Awesome By Ben on 2/18/12Ben would recommend this product to a friendWorks great. Just don't forget to calibrate every once in a while to make sure you're getting the most accurate readings!
Excellent Product By David on 1/28/12David would recommend this product to a friendConnected in 1 minute. Gives me TDS before and after DI. Will be buying single monitor to check incoming supply. Before this I was using handheld monitor but this is more accurate and easier to use. Now I really do know when to change filters an DI resin.
